This project work describes the control strategies of boiler drum level system. The design and implementation of this process is done in the LabVIEW software. Three different types of boiler drum level control system are designed in the Circuit Design and Simulation toolkit of LabVIEW. This work provides insight into the various PID controller design methods such as Zeigler-Nichol method, Tyreus-Luyben method, Internal Model Control (IMC) as well as Fuzzy Logic Controller. Comparative study is made on the performances of the PID tunings methods for the different control strategies. The implementation of IMC in PID and its utilization for handling unstable processes with dead time is also done. An insight to fuzzy logic and its simple implementation as a controller is studied. Fuzzy logic controller is designed using LabVIEW Fuzzy System Designer. It is implemented in set point weighting for proportional term in PID controller. The performance evaluation for fixed weight and fuzzy weight set-point are performed and their performance in important parameters like overshoot, rise time and settling time are evaluated
